BOOK-SHELF.

SPECIFICATION forming part of Letters Patent NO. 448,091, dated March10,A 1891. n

Serial No. 348,030. (No model.)

To all whom t may concern:

Be it known that I, LOUIS SfrocKsTROI/I, of the city of St. Louis,in theState of Missouri, have invented a certain new and useful Improvement inBook-Shelves, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to certain improvements in that class ofbook-shelves which are provided with rollers on which the books rest;and my invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is an elevation illustrative of my invention. Fig. II is ahorizontal section taken on line II II, Fig. I. Fig. III is a verticalsection taken on line III III, Fig. II. Fig.

in the ofce of a recorder of deeds.

IV is an enlarged detail section taken on line IV IV, Fig. II; and Fig.V is a similar view taken on lineV V, Fig. II. Figs. VI and VII aredetail sections.

Referring to the drawings, l represents the bottom, 2 the top, and 3 thevertical partitions, of a case particularly adapted to hold largebooks-such, for instance, as those used Two of the books are shown at 4,Fig. I. If the case has only one row of shelves,3 would represent thesides or ends of the case instead of partitions.

5 represents shelves upon which the books are supported. These shelvesare composed of a horizontal series of rollers 6, (see Figs. II and IIL)the rollers being journaled in strips 7 secured to the sides orpartitions 3 of the case. The books are placed on the shelves, and therollers turn as the books are shoved inwardly into the case. Broadlyconsidered there is nothing new in forming shelves of such rollers. Y

Various means have been devised to prevent the edges of the books frombinding on the sides of the cases or on the partitions 3 as they areshovedinto and pulled out of the iile, and one means which hasheretofore been resorted to is to arrange vertical rollers against whichthe ends of the books would bear. To accomplish this same purpose, butmore cheaply and with less expense of room,y I form Iianges S on theends of the outer roll ers 6 of each shelf, and the inner rollers ofeach shelf` may be provided with like iianges.

The inner face of each flange is' preferably.

made inclined, as shown at 9, Fig. V, so that as the roller is turned bythe inward or outi ward movement of the book theface of the iiangedoesnot rub the ends of the book, as only the baseof each liange bearsagainst the book, as shown at 9, Fig. I. By making the iianges inclinedthe book is also more easily guided into its proper place when puttingit on the shelf. I prefer to make a permanent or tight connectionbetween the rollers and the iianges, so that the two will revolvetogether. By means of these flanges it will be seen that a rolling-surface will be presented to the ends of the book, as well as to theside of the book which rests upon the shelf Composed of the rollers.

It is somewhat difficult to grasp these heavy books when they are intheir inner position on the shelves, and as a means for starting theiroutward movement, so that they can be grasped by the hands, I haveemployed a bar or rod 10 for each shelf. I have shown the inner ends ofthe bars turned upwardly and perforated to receive pins or stems 11, bywhich the inner ends of the bars are supported. (See Fig. III.) Theinner ends of the bars also extend upwardly beyond the pins 1l, as shownat 12, so as to be above the lower faces of the books when in position,(see Fig. III,) and these extensions 12 may be faced with felt or othersuitable material 13 to prevent rubbing the books. Near the outer end ofeach bar is an upright vertical extension 14, perforated to receive apin 15, projecting inwardly from a strip 16, that extends across thecase inside of the front roller. By t-hese pins I5 the outer ends ofvthe bars or rods 10 are supported, and between the extensions orprojections 14 and the bars 16 I prefer to place coil-springs 17, thetendency of which is to hold the bars 10 in their inner position. Theextreme outer end of each bar is preferably turned upwardly and isprovided with a hand-hold or hook 18, which fits, when the bar is in itsinner position, between the inner ends of the outer roll 6, (the outerroll 6 being divided for the purpose of admitting this hand-hold to moveinwardly into line with the face of the outer roller, so that the casewould not be disfigured by the hand holds projecting beyond4 therollers, or, in other words, beyond the outer edges of the shelvescomposed of the rollers.) By grasping the hand-hold 1S and pulling thebar l0 outwardly from the position shown on the second shelf from thetop of Fig. III to the position shown upon the bottom shelf in Fig. IIIthe ybooks are pulledout suiiieiently by this means to permit them to beeasily grasped by the hand and Withdrawn from the oase. As soon asthehandle 18 is released the bar 10 is thrust to its inner position bythe spring 17 out of the Way.

To prevent books coming in contact with the springs 17 or the uprightsor projections 14, I prefer to locate guards 2O over these parts, asshown in Figs. II and III.

To afford additional 'rigidity to the partitions 3, I bind their outeredges by means of a strip 20, as shown in Fig. VI, and after it isappliedI corrugate the strips, together with the edges of thepartitions, as shown in Fig. VII, thus holding the binding on thepartitions and affording greater strength to the partitions at smallexpense.

I claim as my inventionl. A book -case having shelves provided withrollers, one or more of said rollers having flanges at the ends,substantially as and for the purpose set forth.

2. A bool -case having roller-shelves, one or more of the rollers ofWhich have inclined flanges at the ends, substantially as and for thepurpose set forth.

3. A book-oase having roller-shelves and a pull-bar or rod 10, inconnection with a shelf having an upturned inner end, substantially asand for the purpose set forth.

et. A book-case having roller-shelves and a spring' pull-bar or rod I0,in connection with a shelf having an upturned inner end, substantiallyas and 1for the purpose set forth.

5. A book-case having roller-shelves and a pull-bar or rod, inconnection with a shelf having perforated upturned inner ends andextension-pins passing through the perforations, and a spring 17,substantially as and for the purpose set forth.

6. In a book-case, the combination of the roller-shelves, pull-barshaving handles 18, adapted to lit between the inner ends of thesectional outer rollers, and springs for holding the bars in their innerpositions, substantially as and for the purpose set forth.

7 In a book-case having roller-shelves, the combination of pull-bars bywhich the books are Withdrawn and the shields 2O over the pull-barsbetween the front rollers of the shelves, substantially as and for thepurpose set forth.
